Navigating the System

Welcome to the Operating Systems course of the IT Support Professional Certificate! In the first week of this course, we will cover the basics of Windows and Linux operating systems (OS). We will learn about how directories and files work in Windows and Linux OS. You will also learn practical ways to manipulate files and directories in the Windows graphical user interface (GUI), Windows command line interface (CLI), and Linux shell. By the end of this module, you will interact with files and directories and perform basic text manipulation in Windows and Linux OS.

So far in this course we have been using command aliases in PowerShell. PowerShell is a complex and powerful command language, that's also super robust. We've been able to use common aliases, that are exactly the same as their Linux counterparts. But from here on out, we'll need to deploy some advanced command line features, so we'll need to look at real PowerShell commands. You've already seen an example of a real PowerShell command, Get-Help, which is used to see more information about commands. There's another PowerShell command that we can use to look at one of our aliases, that we've been using as our list directory. To see what the actually PowerShell command is that gets executed, we can use the PowerShell command, Get-Alias. Interesting when we call LS, we are calling the PowerShell command Get-ChildItem, it gets or lists the children which are the files and sub directories of the given item. Let us actually run this Get-ChildItem command with the item C:\. You'll see this is the same output as, ls C:\. Cool. PowerShell commands are very long and descriptive, which makes them easier to understand. But it does mean a lot of extra typing, when you're working interactively at the CLI. Aliases for common commands are a great way to work more quickly in PowerShell. We've been using them up to this point to help us hit the ground running with the command line. In Windows, you pretty much have three different ways you can execute commands. You can use real PowerShell commands, or the relatable alias names. Another method that we've mentioned, but haven't really talked about yet is cmd.exe commands. Cmd.exe commands are commands from the old MS-DOS days of Windows. But they can still be run do to backwards compatibility. Keep that in mind, that they aren't as powerful as PowerShell commands. An example of a cmd.exe command is dir. Which coincidentally points to the PowerShell command Get-ChildItem, which is also where, ls Alias gets pointed to. Remember the PowerShell command Get-Help, well there's a command parameter that you can use to get help with command.ext commands, /?. Keep the difference in mind, Get-Help is used for PowerShell commands like Get-Help ls, and /?, is used for other commands like dir/?. If I tried to use, ls/?, it will return nothing, because the PowerShell command that ls is an alias of, doesn't know how to handle to the parameter /?, and vice versa. You're free to use whatever commands you feel comfortable with. But in this course we're going to use common aliases, and PowerShell commands.
